Mechanical pencils. I've had the same one for years and it's the only one I want to use. The erasers all worn down, but I just use my kneaded eraser. Sometimes I'll use water color pencils, if I feel like using color, but generally I prefer pencil and shading.

Highlighter for early sketches and beginning phases, engineer pencil for a more concise sketch.
Then I like to use Faber Castell inking pens. Follow that up with Copics/Prisma colors! I prefer markers but I find colored pencil is great for texture.

Colored pencils are my favorite. I also like markers, mechanical pencil (especially with colored lead) and ink. I love to doodle and mess around in Painter as well. For cell-style coloring, Photoshop is best. =3

* I use 3B for my sketches
* 0.5 Mechanical pencil for detail (so I don't leave out anything important)
* I also use the 2B for shading lines
* Lastly I try to ink the sketch without inking the shading lines... (Bad habit)
* For inking I use a Pigment ink drawing pen or just a black fineliner.
* I like the effect of shadows and clothing in manga so I do the darker clothes in a black marker
* Colouring I use water colour pencils
(Saving up for copic markers for colouring)
